• Write clean, secure, efficient code with proper documentation while ensuring security and performance best practices.
• Design, build and deploy AI agents and agentic workflows (tool use, multi‑step orchestration, human‑in‑the‑loop) that automate analysis, reporting and operational tasks.
• Develop multi‑agent systems on Google Cloud using the Agent Development Kit (ADK), and deploy, scale and monitor them on Google Agent Runtime with proper session, memory, identity and access management.
• Develop reusable plugins, skills and MCP (Model Context Protocol) servers that securely expose our data, APIs and internal tools to AI agents.
• Integrate LLM APIs (Anthropic Claude, OpenAI / Azure OpenAI, Google Vertex AI) into applications, including prompt engineering, structured outputs, function calling and retrieval‑augmented generation (RAG) over enterprise data.
• Configure and govern AI coding harnesses such as Claude Code and GitHub Copilot (instruction files, custom commands, subagents, hooks, MCP integrations) and coach the team on effective agentic development practices.
• Evaluate and monitor AI features (test sets, quality, cost and latency tracking) and apply guardrails and responsible‑AI practices.
• Participate in all phases of the software development lifecycle while collaborating with design and product teams.
• Continuously expand technical knowledge through training while performing code reviews.
• Support the Power BI team with deployment requests.

Preferred Qualifications:

• Experience with Python.
• Experience with RAG architectures, embeddings and vector search.
• Experience with agent frameworks and SDKs (Google ADK, Claude Agent SDK, Semantic Kernel, LangGraph or similar).
